Res., 28, 211 2020 The synthesis of covalently crosslinked hydrogel networks, based on polyethylene glycol, which contain natural zeolite particles as filler and natural bioactive substances from phytoextracts, loaded in situ, in the polymeric matrix. For this study, a rose hip extract Rosa Canina , which is well-known for the antioxidant properties of the phenolic compounds from its composition and for the potential anticancer activity was used. Rosa hip release tests provided significant data to evaluate the potential of slow/controlled delivery of active principles. In this rega...

Res., 28, 257 2020 The addition of methyl-β-cyclodextrin-poly L-lactide MCD-PLLA to PLLA dramatically increased the elongation at break E and toughness UT of PLLA without little affecting its Tg and tensile strength. The highest E and UT were observed for PLLA blends with 12- and 9-arm MCD-PLLAs, respectively.

A facile bead foam processing was developed, from which high quality expanded polypropylene was produced. Processing conditions were examined using a rheological approach, and cell development was observed for samples with different crystallinities and molecular weights in the pilot-scale foaming experiment.

Res., 28, 327 2020 Poly lactic acid PLA was modified by reactive extrusion with tetraethoxysilane TEOS , as silica network. Despite the small TEOS loading, the complex viscosity of PLA/silica hybrids was enhanced clearly compared to that of neat PLA, especially at low shear rate. Also, the η0 was more than doubled by introducing TEOS. Thus, the hybridization of PLA and silica network influenced the rheological properties.

Res., 28, 373 2020 In Diels-Alder DA chemistry, DA bonds formed by cycloaddition of furan and maleimide groups at 60 oC undergo reverse retro-DA rDA reaction at 150 oC. Due to this reversibility, the TiO2/PU nanocomposites containing the DA bonds exhibited thermal self-healing properties after being cut. The dielectric constant and loss, mechanical properties can be effectively restored to their original state after damage.
